8 Claims.

This invention relates to improvements in automatic registering or counting devices for indicating the progress of operation of a machine or other apparatus and for arresting the action of the machine at a predetermined stage by cooperation with the stopping mechanism thereof. One object of the invention is to provide a clock-like registering or indicating device which may be set to cause the machine to perform a 1 definite number of operations and to automatically arrest the functioning thereof upon the completion of the work.

Another object of the invention is to provide a device of the type specified which is efficient and accurate in action to arrest .the action of the machine at a predetermined point in its operation.

In general, the present registering device comprises means for indicating the number of operations of a machine or apparatus to which it is connected and means controlled therefrom to actuate the stopping-mechanism of the machine whatever form of construction the latter may take.

Referring to the drawings, the coil-winding machine herein illustrated comprises a bed or table 2 supporting a headstock 4 carrying Journals 6 and 7 for a rotatable shaft or winding- 30 spindle 5. The shaft or spindle 5 carries a beltpulley 10 which may be connected to be driven from any suitable source of power such as an electric motor, not herein shown. At the opposite end of the winding-spindle 5 is a handwheel 35 15 which is also used as a brake-wheel to effect prompt arrestment of the rotation of the spindle. This end of the spindle 5 carries a socketed chuck 17 for connection with a winding-mandrel or arbor 20 on which the coils C are wound, the opposite end of the mandrel being received in a similar chuck rotatably supported by a tailstock, not herein shown.

The strands of conductor or wire w are fed to the winding-mandrel 20 from above and caused to be traversed longitudinally of the axis of the coils by means of reciprocating guides 22. In the present type of machine a plurality of coils or electric windings are produced simultaneously by providing a series of the wire-guides 22 which are mounted in spaced relationship on a sliding carriage or crosshead 25. The crosshead 25 is reciprocated from a horizontal traverse-rod 26 which derives its motion from a heart-shaped cam 27. The cam 27 is fast with a gear 28 in a train driven from the driving-spindle 5 in the manner as later described. A roll or follower 29 on the stud 33 carried by a block or slide 31 engages a groove 30 in the cam 2'7 and thereby imparts motion to the slide which is reciprocable on an inclined track-arm 32. A second roll on the forward end of the stud 33 engages in a slot 34 in a vertical arm 35 which is secured fast to the traverse-rod 26. The track-arm 32 is pivoted on the axis of the cam 27 and is angularly adjustable along a fixed quadrant 36. By adjusting the angular position of the track-arm 32 the range of action of the slide 31 is regulated to control the extent of reciprocation of the arm 35 and rod 26 whereby to adjust the length of throw of the wire-guides 22 in accordance with the type of coils to be-produced.

The traverse-mechanism of the winding machine is connected to be driven from the windingspindle 5 through the means of gearing as next described, Fast on the shaft 5 is a toothed clutch-collar 38 having its teeth normally engaged with corresponding teeth on the end of a sleeve 39 which is slidable longitudinally of the shaft. A worm 40 on the shaft 5 has its hub keyed to the'end of the sleeve 39 by a tongue and groove connection shown at 42 in Fig. 6. A coiled spring 44, pocketed in a counterbore at the end of the worm 40 and bearing against a washer 45 abutting the end of the bearing-journal 7, normally urges the worm and sleeve 39 in a direction to the left, as viewed in Fig. 6, to maintain the sleeve clutched with the collar 38. These connections provide for the release of the worm 40 from driving engagement with the shaft 5 for a purpose explained in the copending application hereinbefore referred to but for the purpose of the present description the worm 40 may be considered as normally fast with the shaft 5.

The worm 40 meshes with a worm-wheel 46 which is keyed to a stud-shaft 47 journaled in suitable bearings in a portion of the machine frame. The stud-shaft 47 extends through the side of a gear-casing 48, which is bolted to the front of the bed 2 of the machine, and on its forward end carries a pinion 50 fast therewith. The pinion 50 meshes with a spur-gear 51 which is fast with a smaller gear 52 and rotatable on a fixed stud 53 secured in an adjustable arm 54. The arm 54 is adjustable about the axis of the stud-shaft 47 to permit the use of change-gears in substitution for the gears 51 and 52 to alter the ratio of the drive between the spindle and the traverse-mechanism. The gear 52 meshes directly with the large gear 28 which drives the cam 27 and thus motion is transmitted to the earn from the winding-spindle 5 to reciprocate the thread-guides in the manner as previously explained.

As set forth in the copending-application hereinbefore referred to, the winding machine is preferably driven from an electric motor and the starting and stopping of the machine is effected through the use of a contact switch 55, shown in detail in Fig. 8. The switch 55 may comprise a casing or box 56 enclosing opposite contact members 57 and 58, from which conductors 59' and 60 lead to the motor circuit. A plunger-rod 61 is slidable through the casing 56 and normally urged downwardly by means of a coil-spring 62 acting against a washer 63 on the end of the rod, see Fig. 8. The plunger-rod 61 carries a contact element or ring 64 adapted to bridge the gap between the contact members 57 and 58 when the rod is held in raised position as illustrated in Fig. 8. The rod 61 is sustained in this position by means of a starting-lever 65, shown in Fig. 6.

The lever 65 is pivoted at 66 to a lug projecting from the side of the headstock 4 and has a substantially horizontal arm 67 with a slotted lug 68 at its end for receiving the plunger-rod 61, see Fig. 8. A collar 69 fast on the upper end of the rod 61 engages the top of the lug 68 to connect it with the lever 65. The lever 65 has an upright arm '70 terminating in a handle '71, by means of which it may be operated manually to raise the plunger-rod 61 to move the contact ring 64 across the contacts 57 and 58. A coil-spring 72 secured to the arm 67 of the lever 65 is anchored at its opposite end to the machine frame, whereby it tends torock the lever in a clockwise direction, as viewed in Fig. 6, to lower the rod 61 and remove its contact ring 64 from across the contacts 57 and 58 to interrupt the electric circuit to the motor. The lever 65 has an arm 18 extending in the opposite direction from its arm 67 and carrying an adjustable brake-shoe 19, see Figs. 1 and 6, which is adapted to engage the periphery of the brake-wheel 15 when the lever is rocked by its spring 72.

The starting-lever 65 is maintained in position with the, switch closed during the operation of the machine under the control of detent-means as next described. Slidable in bearings 73 and 74 on the casing 48 is a horizontal rod 75. The rod 75 is formed with a slot or opening 76 on its side adapted to receive a key 77 projecting downwardly from the end of the arm 67 of the lever 65, as shown in Fig. 6; it being noted that in this view the connection between the lever 65 and the plunger rod 61 is omitted for the sake of clearness. The rod 75 is urged toward the right, as viewed in Fig. 6, by means of a spring 78 attached to its end, so that when the lever 65 is rocked to raise the plunger-rod 61 the end of the key 77 will engage with the top of the rod to detain the lever in this position. The sliding rod 75 is adapted to be slid in opposition to the tension of the spring 78 by means of a lever 80 which, in the present arrangement of the machine, is employed as the knock-off lever for arresting the drive under the control of the counter or registering device to be later described. The lever 80 is pivoted at 81 to the rearward side of the casing 48 with the end of its lower arm 82 engaging a slot in the side of the rod 75 to slide the latter. At its upper end the lever 80 has a handle 83 by means of which it may be operated manually to slide the rod 75 to stop the machine.

The registering device of the present invention may be mounted on the machine in any convenient location and, as herein illustrated, it is supported from an upright arm or bracket 85 attached to the casing 48. As shown in Fig. 3. the bracket 85 has a boss 86 abutting a machined face on the upper portion of the casing 48 and clamped thereto by means of a stud 87. The stud 87 has a shouldered portion 88 fitted to a counterbore in the bracket 85 with its shank extending through a hole in the latter and in the casing 48 and a nut 89 screwed onto its end. The forward end of the stud 87 serves as a journal for a spur-gear. 90 which drives the counter from the gear train connecting the spindle 5 with the traverse-mechanism of the machine. ring to Fig. 1, the gear 90 meshes with a similar gear 91 journaled on a stud 92 fast in the casing 48. The gear 91 meshes with a smaller spur-gear 93 fast with the pinion 50, previously described as being driven with the worm-wheel 46. The outer end of the stud 87 has a threaded bore engaged by the end of a bolt 94 passing through a bearing 23 for the traverse-rod 26 and the quadrant 36. In this manner the stud 87 acts as a tie between the parts last described and the casing 48.

Refer- Projecting from the top of the bracket 85 are two parallel, spaced, upright pins or rods 95 which serve as a support for slidably mounting the registering mechanism for vertical movement, whereby its operating gear may be carried into and out of mesh with the driving-gear 90 which connects the device with the machine under its control. Slidable on the rods 95 is a frame or bearing-member 96 of bifurcated form having laterally-projecting lugs 98 bored to receive the rods 95. The rods 95 are headed over at their upper ends whereby to limit the upward sliding movement of the bearing-member 96 thereon to prevent the .registering device from being removed from the machine. The bearing-member 96 is formed with a central hub 99 bored to form a bearing for a horizontal shaft 100 which carries a dial-gear 101 fast on its forward end.

The gear 101 is secured fast on the shaft 100 by means of a tapered pin 102 driven through its hub 104, see Fig. 2. The bracket 85 has a rearwardly projecting ledge 84 providing a seat or rest for the head of a screw 97 screwed into the underside of the bearing-member 96. The screw 97 is adjustable to regulate the position of the bearing-member 96 with respect to the bracket 85 whereby to locate the axis of the gear 101 at the correct distance from the axis of the gear 90 so that the teeth on the gears will mesh with the proper clearance to provide for a free turning motion. A check-nut 103 on the screw 97 is set up against the lower side of the bearing-member 96 to lock the screw in its adjusted position. This arrangement insures that when the member 96 is slid upwardly on its supporting rods 95 to disengage the gears it will be thereafter returned to position to properly enmesh the teeth on the gears.

The hub 104 of the gear 101 projects forwardly to receive an arm 105 clamped thereto by a screw 106 extending through its split hub. The arm 105 serves as an index pointer for setting the counter to stop the machine after a. predetermined number of operations and for this purpose its outer end is narrowed and provided with a gauging edge 107 adapted to register with numbered graduations 108 on the forward face of the gear 101. This portion of the arm 105 is beveled off at 109 to adapt it to ride under a plunger-pin 110 during each rotation of the gear 101 as it turns in a clockwise direction as viewed in Fig. 2. The plunger-pin 110 is slidably mounted in a pocket 111 formed in a bearing 112 supported from an elbow-shaped arm 113 which projects forwardly and then laterally with respect to the main portion of the bracket 85. The plungerpin 110 has a stem 114 slidable through the end of the bearing 112 and a coil-spring surrounding the stem is pocketed at the rear of the main portion of .the pin 110 to urge its forward rounded end against the face of the gear 101. In setting the counter the index pointer 105 is carried around in a counter clockwise direction, as viewed in Fig. 2, or opposite to the normal direction of rotation of the gear 101, until the edge 107 of the pointer strikes against the stop-pin 110. This manual adjustment of the pointer is accomplished by raising the bearing-member 96 to release the dialgear 101 from engagement with the teeth of the driving-gear 90, all as hereinafter more fully explained. The shaft 100 projects forwardly from the hub of the gear 101 and is preferably knurled at its end to provide a finger-hold for turning the gear and pointer 105.

On the rearward face of the gear 101 is a camplate 115, fastened by rivets or other suitable means and having an inclined cam-face 116 which is adapted to engage with a trip-lever 117 pivoted on the stopping-lever to move the latter to arrest the operation of the machine, see Fig. 5. Referring to Fig. 7, the trip-lever 117 is pivoted on a screw 118 fast in a lug 119 projecting from the upper arm of the lever 80. A pin 120 projects through a hole 121 in the lever 117 to limit its swinging movement and normally the lever 117 is suspended in the position indicated by dotted lines in Fig. 7 with the pin engaging the top of the hole 121. The lever 117 has a shoulder 122 near its pivot which is engaged by instrumentalities to be later described to rock the lever into operative position as shown by full lines in Fig. 7, whereby to bring its offset end 123 into position to cause the inclined edge 116 of the cam-plate 115 to ride thereacross to move the lever 80 in the manner indicated in Fig. 5.

The trip-lever 117 is shifted into operative position under the action of means carried by a ratchet-disk 125 mounted free to rotate on the rearward end of the shaft 100. As herein shown the ratchet-disk 125 is cut away to form a wheel with spokes 126 supporting its outer rim 127. The disk or wheel 125 has a hub 128 abutting a hub 129 on the rearward side of the bearingmember 95 and a helical spring 130 is coiled around both hubs with its ends fastened respectively to the frame-member 96 at 131 and at 132 to a pin 133 projecting from one of the spokes of the wheel or disk 125. The spring 130 acts to return the ratchet-disk 125 to first position in resetting the counter after the completion of a cycle of operations of the machine and the pin 133 serves as a stop to limit the return movement of the disk in the manner as later explained.

Fast on the rearward end of the shaft 100 is a collar 134 formed with an eccentric hub-portion 135 abutting the rearward face of the disk 125.

The eccentric 135 operates as a cam for oscillating a lever 140. from which motion is transmitted to rotate the ratchet-disk 125. The lever 140 has a hub 141 pivoted on a stud 142 which is fast in a boss 143 at the lower end of the arm or bracket 85, the hub 141 of the lever passing through an enlarged opening in the casing 48. The upper end of the lever 140 is forked to straddle the periphery of the eccentric 135 and as the shaft 100 is rotated with the gear 101 the lever is oscillated from the eccentric.

A pawl 145 pivoted on a pin 146 projecting from the side of the lever 140 has its toe arranged to engage with the relatively fine teeth 14'? on the ratchet-disk 125. The pawl 145 is maintained in engagement with the teeth 147 of the ratchetdisk 125 under the action of gravity, being provided with a Weight-arm 148 extending outwardly from its pivot. The weight-arm 148 is slit to provide a finger 149 which is bent around to engage the edge of the lever 140 to limit the swinging motion of the pawl under the action of its weight. To prevent retrogressive movement of the ratchet-disk or wheel 125 a fixed pawl 150 is provided for successively engaging its teeth 147. The pawl 150 projects from a stud 151 held in a plate-member 152 which is adjustably mounted on the rearward face of the ledge 84 of the bracket 85 by means of a screw 153 and a stud 164 extending through slots 154 in the plate. The plate 152 has a rearwardly projecting finger 136 which is engaged by the flatted side of the stop-pin 133 to limit the turning movement of the ratchet-disk 125 under the impulse of the coil-spring 130 when the counter is reset. By loosening the screw 153 the plate 152 may he slid laterally to adjust the stop-finger 136 to regulate the starting position of the ratchet-disk 125. A screw 165 threaded through a lateral hole in the stud 164 bears against the end finger 136 of the plate 152, see Figs. 3 and 6. The screw 165 is turned to slide the plate 152 to secure a micrometer-like adjustment thereof in setting the stopfinger 136 in position.

The means for throwing the trip-lever 117 into position to be operated upon by the camplate 115 on the gear 101 consists in an element 155 which is adjustable to different positions around the ratchet-disk 125. As herein shown the member 155 is constructed as a quadrantshaped plate adapted to seat against the forward face of the rim 127 of the wheel 125 and provided with an arcuate slot 156 for receiving a screw 157. The forward face of the ratchet-disk 125 is marked with graduations corresponding in numher to the number of teeth on its periphery.

In the present form of construction the ratchetdisk 125 has two hundred and sixty teeth which are numbered in units of ten from 0" to 25". Referring to Fig. 4, the face of the ratchet is scored with an annular groove 15B and the graduations are marked off on either side thereof to provide for greater ease of reading. Stated briefly, there are ten graduations for each numbered unit alternating on opposite sides of the groove 158 and-corresponding to the teeth on the periphe v of the disk. Corresponding with the numbered units of graduations are a series of threaded holes 159 for receiving the screw 157. Riveted to the forward face of the plate 155 is an arcuate strip 161 formed at one end with an inclined lip or projection 162, see Fig. 3, which is adapted to engage the shouldered abutment 122 on the triplever 117 to rock the latter into the position illustrated by full lines in Fig. 7. The heads of the rivets 160 project from the rearward face of the plate 155 into the groove 158 in the disk 125 to prevent the plate from turning on its fasteningscrew 157.

The element 155 is adjusted in position on the ratchet 125 by removing the screw 157, shown in Fig. 4, and sliding the element with the heads of the rivets 160 riding in the groove 158. One end of the plate 155 is beveled off at 163 to provide a gauging edge adapted to register with the graduations on the rim of the disk 125. After the element 155 has been adjusted to position in accordance with the required setting of the counter the screw 157 is inserted in the appropriate hole 159 and tightened in place to hold the plate in its adjusted position. The manner of setting the counter to stop the machine after a predetermined number of operations is explained more fully hereinafter.

The method of operation of the winding machine and its control by the counter or registering device is as next explained. In the embodiment of the invention as herein illustrated the counter is employed for registering the number of revolutions of the winding-spindle, and thereby the number of turns in the electric coils produced on the machine, and to arrest the operation of the winding machine at the completion of a coil of any given number of turns or convolutions. The present drawings, see Figs. 2 and 4, illustrate the counter as set arbitrarily to stop the machine after thirty-five hundred and ninety-five turns have been wound into the coils. The graduations on the dial-gear 101 correspond in spacing to the teeth on its periphery and as herein shown the gear has one hundred teeth and the ratio of the gearing which drives the counter from the winding machine is such that the gear 101 is turned through the space of one tooth at each rotation of the winding-spindle. It will be apparent, therefore, that each graduation on the dial-gear 101 indicates one revolution of the windingspindle and a complete turn of the gear will register one hundred turns of the spindle. During each rotation of the gear 101 the eccentric 135 driven therefrom oscillates the arm or lever 140 to advance the ratchet-wheel 125 through the space of one tooth on the ratchet. The ratchet 125 has two hundred and sixty teeth as before noted, and each graduation on its face represents one hundred turns of the winding-spindle as registered by a complete revolution of the dial-gear 101. As the graduations on the disk 125 each represents one hundred turns of the spindle, a

complete rotation of the ratchet registers twentysix thousand revolutions of the winding-spindle.

In setting the counter to stop the machine after thirty-five hundred and ninety-five revolutions of the winding-spindle, as herein arbitrarily chosen for illustration, the pointer 105 is turned to register with the graduation marked "95 on the dialgear 101, see Fig. 2, and the stop-member 155 is set at the fifth graduation beyond the mark 3 on the outer rim of the ratchet-disk 125, as shown in Fig. 4. With this setting the counter will be operated to arrest the action of the winding machine when the disk 125 registers thirty-five hundred revolutions of the spindle and the gear 101 the additional ninety-five turns thereof. It has been explained that the pointer 105 is adjusted to position on the dial-gear 101 by loosening its screw 106 to allow it to be turned on the hub 104 of the gear; after which the screw is tightened to secure the pointer in fixed position with respect to the gear. The member 155 is adjusted around the face of the ratchet-disk 125 by removing its screw 157 and placing it in the proper hole 159 to register the beveled edge of the member with the proper graduation, it being understood that the fine adjustment of the member 155 is accomplished by sliding the plate on the screw 157. After the counter has been adjusted in the manner as above explained it is set for operation by manual manipulation as next described.

The operator grasps the forward knurled end of the shaft or spindle 100 and lifts it to raise the bearing-member 96 to release the teeth of the gear 101 from the teeth on the gear 90. The raising of the member 96 likewise releases the teeth on the ratchet 125 from the pawl 145 which has only a limited range of movement as controlled by its stop-finger 149, see Fig. 4, and also releases the ratchet from the fixed check-pawl 150. Immediately upon its release the ratchet-disk 125 will be turned in a clockwise direction, as viewed in Fig. 4, under the tension of the spring 130; it being understood that the spring is wound up on the hub 128 of the ratchet during the normal turning movement of the ratchet-disk in a counterclockwise direction. The spring 130 turns the disk 125 backward until its pin 133 strikes against the finger 136 on the plate 152. The disk 125 will thus be held in starting position and meanwhile the operator turns the spindle 100 to swing the pointer 105 around in a counterclockwise direction until its edge 107 brings up against the side of the plunger-pin 110. Upon the completion of this operation the end of the spindle 100 is released to allow the bearing-member 96 to slide downwardly on its supporting rods 95 until its limiting screw 97 strikes against the top of the ledge 84 on the bracket 85. The teeth on the gears 101 and 90 will then be enmeshed to connect the counter to be driven from the machine.

After a winding-mandrel 20 has been placed in the machine and the strands of wire w or other conductor have been led from the supply through the guides 22 and attached to the mandrel the machine is ready for operation. To start the machine the operator grasps the handle 71 of the lever and rocks the latter against the action of its spring 72 to raise the key 77 out of the slot 76 in the side of the slide-bar 75. This operation of the lever 65 draws the plunger-rod 61 upwardly through the switch-box 56 to cause its contact element 64 to close the gap between the contacts 57 and 58 whereby to complete the electric circuit to the motor. Upon the closing of the switch the motor is energized to drive the winding-spindle 5 from its belt connected to the pulley 10.

As the lever 65 is lifted to close the electric switch the bar is slid to the right, as viewed in Fig. 6, under the action of its spring 78 and the key 77 will thereby be caused to engage across the top of the bar to maintain the starting-lever in position with the machine operative. During the sliding movement of the bar 75 the stoppinglever 80 is rocked into position for cooperation with the tripor knock-off devices of the counter,

As the winding machine operates to wind the wire onto the coil-mandrel 20 while traversing the strands axially thereof by the reciprocation of the carriage 25, in the manner as previously explained, the windings will be built up in overlying layers and usually sheet insulation, such as paper, is inserted into the coils after the completion of each layer. The machine continues to operate in this manner with the registering device or counter driven therefrom through the train of gears 93, 91 and 90, previously described.

It has been explained that the dial-gear 101 turns in a clockwise direction, as indicated by the arrow in Fig. 2, and during its rotation the beveled end 109 of the pointer 105 will ride under the stop-pin 110 to cause the latter to slide back in its pocket to permit passage of the pointer. As the dial-gear 101 turns through a complete revolution it effects an oscillation of the arm or lever 140 to advance the ratchet-disk 125 one tooth under the impulse of the pawl 145. With the counter set in accordance with the reading of the present illustration, as above explained, after the gear 101 has been turned through thirtyfive complete revolutions the ratchet-disk 125 will have been advanced in a counterclockwise direction to a sufficient extent to engage the finger 162 on its forward face with the shoulder 122 of the trip-lever 117 to rock the lever into the position shown by full lines in Fig. 7. Now, as the gear 101 continues its rotation throughout the space of ninety-five teeth the cam-plate 115 on the gear will finally be brought around into position to engage the offset or bent end 123 of the trip-lever 117 in the manner illustrated in Fig. 5. This engagement acts to force the upper arm of the lever 80 to the right, as viewed in Fig. 6, whereby to slide the rod 75 to the left to bring its slot 76 into alinement with the key 77 on the lever 65.

Immediately the slot 76 is brought into position beneath the key 77 the lever 65 will be released and swung downwardly under the force of its spring 72 to cause the plunger-rod 61 carried at its end toslide down through the switch-box under the impulse of its spring 62. The contact element 64 is thus removed from across the contacts 5'7 and 58 to break the'circuit and interrupt the flow of current to the motor. As the switch is opened the motor ceases to function and the machine is brought to a prompt stop by means of the brake-shoe 19 on the lever 65 which operates against the wheel15 on the spindle 5. It has been explained that the plate 152 shown in Fig. 4 is adjustable to regulate the position of the stop-finger 136 which determines the initial or starting position of the disk 125 and through this adjustment the counter may be set very accurately to arrest the operation of the machine precisely at the completion of the number of revolutions of the winding-spindle required.

After the completed coils have been removed from the machine, the latter supplied with a fresh winding-mandrel and the wire connected thereto in the manner as previously described, the counter is reset for another cycle of operations. The resetting is readily and conveniently accomplished by merely lifting the spindle 100 and turning the pointer 105 back into DOS'ltlul'i to engage the stop-pin 110, it having been ex-.

plained that the return of the ratchet-disk 125 is accomplished automatically by the spring 130 without requiring attention on the part of the operator. When once adjusted for controlling the operation of the machine the counter requires no further attention but will operate repeatedly to stop the machine after the predetermined number of turns have been wound into the coils.

It will be observed from the foregoing that the present improved registering device is of simple construction without complication in its gearing and therefore less liable to derangement and getting out of order and more durable in use than previous devices of a like nature.

The indicating means are easily set and reset for continuous operation of the machine and the device functions with great accuracy and precision to control the operation of any type of machine to which it may be applied.

While I have herein described and illustrated the improved device as embodied in a preferred form of construction, and as applied to a certain specific use, it is to be understood that the counter may of itself be modified in form and construction and applied to various other uses without departing from the spirit or scope of the invention. Therefore, without limiting myself in this respect, I claim:

1. In a device of the type specified, the combi nation of a gear, a cam-member carried by said gear, a stop-member, a trip-lever on said stop member adapted to be thrown into position to be engaged by the cam-member to move the stopmember, a member driven from the gear at a different rate of movement, and means on said last-named member to throw the trip-lever into position to be engaged by the cam-member after a predetermined number of rotations of the gear.

2. In a device of the type specified, the combination of a registering element, a second registering element, means for driving said registering elements at different rates of movement, a shiftable member for operating the stopping-mechanism of a machine, a trip-member adapted to be thrown into position to be operated upon by the first registering element to move the shiftable member, and means on the second registering element for moving the trip-member into operative position.

3. In a device of the type specified, the combination of two rotatable registering elements, means for driving said elements with different rates of'r'novement, a shiftable member for operating the stopping-mechanism of a machine, a cam on one of the registering elements, a tripmember adapted to be thrown into position to be engaged by the cam to move the shiftable member; and adjustable means on the other registering element for moving the trip-member into operative position.

4. In a device of the type specified, the combination of two rotatable registering elements, means to rotate said elements at different rates of speed, a shiftable stop-member for operating the stopping-mechanism of a machine, a triplever pivoted on said stop-member, means on one of the registering elements for engaging the trip-lever to shift the stop-member, and means on the other registering element for setting the trip-lever in position to be operated upon by the engaging means on the first registering element.

5. In a device of the type specified, the combination of two registering elements, means for rotating said registering elements at different rates of speed, a lever for operating the stoppingmechanism of a machine, a trip-lever pivoted to said stopping-lever, means on one of the registering elements for engaging the trip-lever to move the stopping-lever, and means on the other registering element for moving the trip-lever into position to be engaged by the means on the first registering element.

6. In a device of the type specified, the combination of a gear, a ratchet, means to drive the ratchet from the gear with a different rate of motion, a stop-lever for operating the stoppingmechanism of a machine, a trip-lever on the stop-lever, a cam on the gear for engaging the trip-lever to move the stop-lever, and adjustable means on the ratchet for engaging the trip-lever to move it into position to be engaged by the cam on the gear.

'7. In a device of the type specified, the combination of a gear provided with graduations on its face, a pointer adapted to be adjusted around the gear to register with the graduations thereon, a stop-pin for engaging the pointer in setting the gear in starting position, a ratchet driven from the gear with a different rate of motion, means actuated from the gear to operate the stoppingmechanism of a machine, and means on the ratchet for throwing said last-named means into position to be actuated by the gear.

8. In a device of the type specified, the combination of a gear, index-means adjustable around the circumference of the gear, a stop for limiting the movement of the index-means to set the gear in starting position, a wheel driven from the gear with a different rate of motion, a shiftable member for operating the stopping-mechanism of a machine, a trip-member operable to move the shiftable member, means adjustable on the wheel to throw the trip-member into operative position, and means on the gear for engaging the trip-member to move the shiftable member.
